spread like wildfire through the city: Gylippus was coming, armed with full authority from Sparta--Corinth had taken up their cause--Syracuse was saved! All thought of surrender was instantly flung away, and news arriving shortly afterwards that Gylippus was near at hand, the whole Syracusan force marched out to meet him, and escorted him triumphantly into the town. Thus, without a blow being struck, an immense access of strength had been brought to the besieged, and the grand condition of successful resistance, on which Alcibiades had laid such weight, was fulfilled. A Spartan officer of consummate ability was now in Syracuse, and he had made his way into the city, not alone, not by stealth, but at the head of an army, and before the very eyes of the enemy. Weeks must have elapsed between the departure of Gylippus from Leucas, and his arrival at Syracuse; and during all this time, with one trifling exception, Nicias made no effort to oppose his progress. Prudent men might well have regarded the enterprise of Gylippus as a wild and desperate adventure; and such it must have proved, but for the astounding blindness and apathy of Nicias. At the time when Gylippus reached Syracuse the Athenian lines of circumvallation were all but completed on the side of the Great Harbour; but a wide interval was still left between the Circle and the northern sea, and it was here that Gylippus had effected an entrance. To keep this space open was a matter of supreme importance, and the scene of action is now shifted again to the northern slope of Epipolae. On the day after his arrival Gylippus succeeded in capturing the Athenian fort at Labdalum, and the command of this position gave increased facilities for the construction of a third counterwall, which was forthwith taken in hand, and carried in the direction of Labdalum, until it crossed the blockading line at its northern end. If the Syracusans succeeded in completing and holding this counterwork, the blockade of Syracuse would be rendered impossible. Yet for some time Nicias made no attempt to interrupt its progress. As if already convinced of his inferiority in the field, he took steps to keep his communications open by sea, and with this object he employed a part of his forces in fortifying the headland of Plemmyrium, which commanded the entrance to the Great Harbour. Here he built three forts which served as an arsenal for the Athenian stores; and henceforth Plemmyrium became the chief station for his fleet. This removal had a disastrous effect on the Athenian crews; for the place being almost a desert, and the springs distant and scanty, they were compelled to go far from their quarters in search of forage and water, and while thus engaged they were cut off in great numbers by the Syracusan horse, who had been posted at Polichne for this purpose. A rapid demoralization of the crews was the consequence, and desertions became more frequent every day.
